Sounds like uprez-stack-and-average in Photoshop, or PhotoAcute. Both will produce similar resolution with the right technique and image. I do it all the time. I easily make 30x20 prints from Mavic Pro (12MP) stacked files. With an ILC I've gone over 40" and could go much larger if I had the room for it. 
Hi Bob.
Thank you very much for the suggestions here, I do very much appreciate it.
I test those algorithms too. The second image is a large leap forward from anything previously obtainable and is a comprehensive proprietary technique we have innovated yet not disclosed yet (we will reveal it in The Ultimate Mastering Fine Art Printmaking class in Vegas at the end of March). I can understand how you might think you could produce the second result, but the original files lack of information and lack of quality was more substantial than you might be thinking. Literally, the first (the bad one) image cannot be beat (but can be nearly matched) with the aforementioned approaches. It is best of the best of every algorithm tested (including the ones you have listed) and then taken through every sharpening protocol you can imaging (Deconvolution, 5 or more types of advanced Highpass, Unsharp Mask, Edge Sharpening, Smart Sharpening, 3rd Party Sharpening and one and on...) to ensure each of the upsizes reached their fullest potential. The original File in Photoshop had literally many tens of layers with every upsize method a person can get their hands on (with ideal finished sharpening appropriately applied). It was immediate that this technique was a light year jump ahead of everything. All other top contenders were similar to each other but a gigantic step back!
Each year (throughout the year) I (and some others) go through a full list of interpolation algorithms. Most of these (these are not the brand names...):
All relative Bicubic algorithms, Nearest-neighbor interpolation, Lanczos, Hybrids, Sinc, new Ai Methods, Bilinear, Box
Mipmap, Fourier-transform methods, Deep convolutional, Neural Networks, Edge Guided, DWT based, Threshold-based, Multistep techniques...
And although Ai is making some incredible ground right now (sometimes beating everything in certain areas) it is far too unruly, uncontrollable and inconsistent at this point.
If you want to see this in Vegas, come check it out.

! Thank you, Ryan, for the needed laugh!
